GATE-HINGE.

Specification of Letters Patent.

Patented Apr. 2, 1918.

Application filed December 26, 1916.. Serial No. 138,700.

To all whom it may concern:

Be it known that we, JOHN S. BARNES and Eocnn'r J. RANDALL, citizens ofthe United States, residing at Detroit, county of Wayne, State ofMichigan, have invented a certain new and useful Improvement inGate-Hinges, and declare the following to be a full, clear, and exactdescription of the same, such as will enable others skilled in the artto which it pertains to make and use the same, reference being had tothe accompanying drawings, which form a part of this specification.

Our invention relates to gate hinges shown in the accompanying drawingsand more particularly pointed out in the following specification andclaims.

One of the objects of this invention is to provide a device formed ofsheet metal by suitable blanking and forming dies that a finishedproduct may be rapidly obtained at a minimum manufacturing cost andwithout the necessary refinishing or drilling as required by manydevices of this character formed of malleable or cast iron.

Another object of the invention is to pro vide a construction adapted tomeet the requirements of tubular gate frames of vary ing diameter sothat when brought under tension by the adjustment of a connecting bolt,the respective members forming the device securely grip the gate frame,while permitting the portion sleeved upon the hinge pintle to freelyrotate thereon.

\Vit-h the foregoing and other objects in view which will appear as thedescription proceeds, the invention resides in the combination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes may be made inthe precise embodiment disclosed hereby without departing from thespirit of the invention.

In the accompanying drawings forming part of this specification Figure 1is an elevation of the device as it appears upon leaving a blanking die.

Fig. 2 is a perspective view of the completed device showing a fragmentof a gate frame, and its hinge pintle in dotted lines.

Fig. 3 is a cross-sectional view through a tubular gate frame and bingepintle, showin the device clamped to the frame.

lieferring now to the letters of reference placed upon the drawings 2-A, denotes a tubular gate frame, and B,

a hinge pintle, both being indicated in dotted lines in Fig. 1.

C, O, designates a pair of coacting members constructed of sheet metalhaving arcshaped ends D, and D ;the portions D, of the respectivemembers being interlocked as indicated at cl, and tightly clamped uponthe frame A, by a transverse bolt E, projecting through an aperture 0,provided in the wall of each portion between their areshaped ends. Thedotted lines in Fig. 3 serve to indicate that the walls of therespective members are sufficiently resilient to admit of being drawntogether by the adj ustment of the bolt whereby the device may besecurely clamped upon the gate frame;- the diameter however of thatportion of the device surrounding the hinge pintle being sufficientlylarge to admit of its freely turning thereon.

It will be noted that in forming the device the wall at c, is raised toprovide a relatively wide surface against which the head of the bolt andnut may bear ;-the surface being level with the periphery of thearc-shaped portion surrounding the hinge pintle.-1hus a common form ofwrench may be used for adjusting the nut to clamp the device upon a gatef 'ame.

Having thus described our invention what we claim is 1. A device of thecharacter described comprising a pair of coacting sheet metal membershaving are-shaped ends, the areshaped ends of the members at'one end ofthe device having an interlocking connection consisting of a slot formedin one member and a tongue on the other member adapted to fit in saidslot, each member between its arc-shaped ends being raised to the levelof the surface of one of the arc-shaped ends and forming a relativelybroad surface, said members being perforated through said raisedportions, a headed bolt passed through the perforation and having itshead bearing against the respective broad surfaced raised portion, and anut having working fit on the bolt and bearing against the broadsurfaced raised portion of the other member, whereby said members may beadjustably clamped upon a gate frame and upon a hinge pintle.

2. A device of the character specified, comprising similar membersformed of sheet metal blanks, each member having its end portionspressed. outwardly to form re cesses, which unitedly provide openingswhen the members are placed together; and

having portions intermediate the recesses pressed outwardly andapertured, and one of the members having 2]. terminal tongue and theother a terminal matching opening to receive the tongue, whereby toprovide an interlocking connection between the members flush with theirinner and outer Walls, and securing means passing through.

Sonics of this patent may be obtained for five cents each, by addressingthe Commissioner of Patents,
